Patented Mar. 16, 1915.

Application filed March 21, 1906, Serial No. 307,186. Renewed July 7,1910. Serial No. 570,906.

To all whom it may concern Be it known that I, OSCAR RonsEN, a c1t1- zenof the United States, residing at New York, county of New York, andState of New York, have invented certain new and useful Improvements inPrintingMachlnes, fully described and represented in the fol lowingspecification and theaccompanymg drawings, forming a part of the same.

This invention relates to certaln lmprovements in printing machines.

It is frequently necessary to associate with the product of a printingmachine pages bearing subject-matter which cannot be placed or which itis not desirable to place thereon by the cylinders which produce theprinted pages. Thus, for instance, it is desirable frequently tointroduce into a magazine advertising pages printed in color Wl11Cl1cannot well be printed, if at all, on the cylinders of the machine whichproduce the remainder of the advertising pages, or it may be desired toassociate with the said printed pages a cover executed in such a mannerthat it cannot be printed on the machine in which the magazine isprinted.

It is the object of this invention to produce an improved printingmachine in which a web or webs may be printed, forwarded and manipulatedin such a way as to produce a product consisting of a plurality of pliesor pages, and in which there may be united or associated with thisproduct sheets which are fed from a pile, or, if desired, from aplurality of piles.

With this and other objects in view, the invention consists in certainconstructions, and in certain parts, improvements and combinations aswill be hereinafter fully described and then specifically pointed out.

Referring to the drawings-Figure 1 is a plan View of so much of aprinting machine as is necessary for an understanding of the invention;Fig. 2 is an end elevation of part of the printing machine illustratingthe invention in detail.

Referring to the drawings, it may be remarked that the particular typeof printing mechanism with which the invention is em ployed may bevaried. As shown, the printing mechanism embodies two couples comprisingprinting cylinders 1 and impression cylinders 2, the cylinders carryingthe necessary plates to produce twelve pages printed and perfected. Athree wide web, marked WV, is led to these cylinders from the otherroll, and is slit into three parts by slitters marked 3, 4c. The usualgearing for driving the cylinders and the slitter is illustrated, but asthis gearing is well-known to those skilled in the art, a description ofitis unnecessary. The slitters, in the particular machine shown,converts the web into three parts marked W, W W These parts are led overturner bars 5, 6 and 7, in the usual and well-understood way and thenover guides 8, 9 and 10, these webs being, by the action of these barsand guides, superposed. The webs are then directed by means of suitableguides to a pair of rolls 11, and from these they pass between a pair ofdrawing rolls 12.

The web manipulating and forwarding mechanism so far described iswell-known in the art and any other mechanism by which a web or webs maybe forwarded and manipulated to produce a product comprising a pluralityof plies may be substituted therefor.

In the particular construction shown, the web manipulating and forwardmechanism further includes a pair of cutting and collecting cylinders13, 14:, the collecting cylinder being marked 13 and the cuttingcylinder 14. The train of gearing indicated at 14 is so proportionedthat the cutting and collecting cylinders make two revolutions betweeneach folding operation so that a product of twenty-four pages, so far asthe web product is concerned, is produced. The collecting cylinder isprovided with the usual folding off blade, indicated in dotted lines at15, in F ig. 2, and also provided with the usual cutting woods indicatedat 16 in the same figure, the knife on the cutting cylinder beingindicated in dotted lines at 17.

Machines embodying the invention will include means for supporting oneor more piles of sheets. In the particular construction illustrated, themachine is designed to support two piles of sheets, the supportingplatforms being marked 18 and 19 respectively. The means by which thesheets are supported may be brought within range of the automaticfeeding means, when such means are employed, in any suitable manner. Inthe construction shown, two screws 20 and 21 are provided for thispurpose, these screws being driven by gearing indicated at 22 and 23.This gearing is driven in any suitable intermittent manner from anyconvenient moving part of the machine.

In the best constructions, and as shown, the sheets will beautomatically fed from the pile or piles, the automatic feeding meansbeing of any desired description. In the particular constructionillustrated, the means for feeding the sheets from each pile isidentical, and therefore a description of one will do for both.Referring to these feeding means, a shaft 24 is provided on which ismounted sheet feeding rolls 25. This shaft 24 is mounted in arms 26which project from a shaft 27 mounted in exten sions of the side frames.One of the arms 26 has connected thereto a rod 28 which is connected tothe arm 30 of a bell-crank lever 29, 30 suitably mounted in the frame.The upper bell-crank lever is operated at suitable times by a cam 31mounted on a shaft 32 which will be hereinafter referred to. The lowerbell-crank lever 29, 30 is operated'at suitable times by a cam 33, thiscam being mounted on a shaft 34 and being driven by a suitable gear 35which is in mesh with one of the gears of the train 14 before referredto. The shaft 27 is provided with a broad faced gear 36 which, throughan intermediate 37, drives a gear 38 on the shaft 24, so that this shaftis constantly revolving.

This broad faced gear 26 is driven through an intermediate 39 from agear 40 on a shaft 41 which will be hereinafter referred to. The shaft24 is moved in a direction opposite to the movement produced by theconnections from the cam 31, by a spring rod construction 42 of theordinary type.

In order to prevent more than one sheet being removed from the pile at atime, a detent, indicated at 43, may be provided, this detent beingcarried on a rod 44 which is pivoted to an arm 45 journaled on a shaft46 which is suitably supported in extensions from the side frames, theconstruction being a well-known one. I

In the construction so far described, it will be seen that at suitabletimes, controlled by the speed of rotation of the cams 31 and 33, therolls 25 will be brought into contact with the upper sheets of the pilesand the sheets automatically fed therefrom.

While the relation between the feeding rolls and the cylinders of theprinting machine may be varied as desired, in the particularconstruction illustrated, the sheets are simultaneously fed from thepiles and fed at a less speed than the speed of the cylinders, and arethen speeded up so that'the sheets, before association in the manner tobe hereinafter described, are running at the speed of the web. Then itis desired to feed the sheets from the piles at less than the speed ofthe cylinders and then speed the sheets up, the mech-anismemployed maybe varied within wide limits, In the particular constructionillustrated, the sheets from the upper pile are delivered to a tapedpathway consisting of upper tapes'47 and' 1 lower tapes 48. The uppertapes pass around a roll 49 on the shaft 41 before referred to andaround collars 50 which are loose on a shaft 51. This shaft 51 is anidle shaft and is mounted in arms 52 suitably supported on a shaft-53,the position mounted on a shaft 55, this roll and shaft being directlyunder the roll 49 and shaft 41 before referred to.- The shaft 55 isprovided with a bevel gear 56 and with a spur gear, (not shown) whichmeshes with the gear 40 before described as on the shaft 41, this gearbeing the gear which drives the intermediate 38. The tapes 48 also passaround collars on a shaft 57 which is in operative relation with theshaft 51'before referred to. This shaft 57 carries a bevel gear 58 whichmeshes with a bevel gear 59 mounted on an inclined way-shaft 60. Thisinclined way-shaft 60 carries at its upper end a bevel gear 61 meshingwith the gear 56 on the shaft 55. It will be observed that the bevelgear 59 is larger than the bevel carried on arms 66, these arms beingmounted on a shaft and maintained in position by a spring rodconstruction 67 of the usual type. The lower tapes 63 run around collarswhich are fast on the shaft 57 before referred to, and then around aroll 68 on" a driven shaft 69, the roll 65 being in 00- operativerelation with this roll 68. The

cutting cylinder 14 drives a shaft'70 to be hereinafter referredto, andthis shaft 70" is intergeared with shaft 69. The shaft 69 is providedwith a gear which isinmesh with a gear 71 on a shaft 72, this gear 71being in mesh with a gear 73 on the shaft 32 before referredto ascarrying the cam 31'. This gear 73 is also in mesh with an intermediate74 which meshes with a gearon and. drives the shaft 57 before referredto.

The gearing onthe shafts 69, 7 O the gear 71 and the gears 73 and 74 areso related to each other that thetapes 62, 63- run at the'speed of thecutting cylinder and-consequently at the speed of the web. 'The sheetsfromthe tapes 62, 63 run over a guide 75' and arethen delivered betweencutting cylinder 14 and a 'roll 76 which coeperates therewith. Thesheets from' the lowerpile are, in the isoparticular machineillustrated, delivered by the feeding rolls between upper and lowertapes 76, 77, the lower tapes running around rolls on a shaft '78, thisshaft carrying a bevel gear 79 which is in mesh with a bevel gear 80 onan inclined way-shaft 81. This shaft carries a bevel gear 82 in meshwith a bevel gear 83 on the shaft 7 2 before referred to, the gears 79,80, 82, 83 being so proportioned that these tapes run at half the speedof the web. The tapes 77 pass around collars on a shaft 84 suitablysupported in the frame of the machine. The upper tapes 7 6 run around aroll 85 which is mounted on a shaft intergeared with the shaft 78, andalso around a roll 86 which is suitably supported in the frame above thecollars on the shaft 84. The sheets, therefore, are delivered from thelower pile which it may be remarked is intended, in the machine shown,to represent a pile of covers. The shaft 7 O which has been referred toas driven by the cutting cylinder 14 has a roll 87 thereon, this rollcooperating with a roll 88 mounted in arms 89 supported on the shaft 84:before referred to, this roll being held in position by a spring rodconstruction 90 of the ordinary type. A guide 91 is employed to directthe sheets from the rolls 87, 88 around the cutting cylinder 14.

With the mechanism so far described, it will be understood that thesheets from the piles are automatically fed therefrom at half the speedin which the web runs through the machine and that they are brought upto the speed of the web as they reach the cutting cylinder 14. Theguides 75 and 91 terminate at the bite of the roll 76 and the cuttingcylinder. The pile sheets therefore are delivered between the cuttingcylinder and this roll 92 and are carried around by the cuttingcylinder, this cylinder being provided with the usual pin construction.

In the particular machine shown, the upper pile is intended to representinner sheets which may be printed in any desired manner, and the lowerpile is intended to rep resent cover sheets. In the operation of themachine, therefore, it will be understood that as the webs WV, VV passbetween the cutting and collecting cylinders, the cylinders operate tofirst cut into sheet lengths the webs which are carried around thecollecting cylinder on its first revolution. On the next revolution ofthe cylinder, the head of the sheet lengths thus cut meet the heads ofthe webs and at this time the sheets from the piles have been forwarded,so that their heads meet the heads of the webs. The sheet lengths on thecollecting cylinder, the webs and the sheets from the piles thereafterpass between the cutting and collecting cylinders, after which the webis again severed. There is at this time on the collecting cylinder 13therefore a product consisting of six web lengths, a sheet from theinner pile of sheets, and a cover sheet from the cover pile. At theproper time, the folding blade 15 is operated to tuck this productbetween the folding rolls 93 which are of the usual type, and the sheetspass down along the guide 94 to a rotating fly 95. By this fly they arerun off on carrier tapes 96, all these parts being of the usualconstruction. It will be understood, therefore, that the particularmachine shown produces a product comprising twenty-four pages printed onand cut from the webs, four pages supplied by the sheets from the innerpile, and a cover, or, in all, a twenty-eight page product having a fourpage cover. It will be readily understood that by causing the cylinder13 to fold off on every revolution instead of collecting, and bychanging the time of the sheet feeding devices for the piles, so thatthe sheets will be removed from the piles successively instead ofsimultaneously, a product can be produced consisting of twelve printedpages and a cover, each pile in that case containing cover sheets. Thechanges referred to are so simple and so obvious that they are notillustrated.

The mechanism by which the invention is carried into effect may bevaried within wide limits. The invention is not, therefore, to beconfined to the specific machine illustrated. It is to be regardedsimply as a preferred mechanism for carrying the invention into effect.
